how to set updates

Wondering how to keep the atv automatic updates, on or off?

Maintenance --> Settings menu.

ok, thank you,
but what I am asking if they’re supposed to be on or off…
I mean: can I update my atv os anytime without messing with the atv flash plugins

It’s best to leave the update feature disabled. aTV Flash will need to be reinstalled when updating the AppleTV software.
